I love that, it's the short version of Patchy's dress, it's quite common in fanart. And the costume is very well made, that deserves credit.

Patchy is weak but not necessarily innocent. go read Bohemian archive in Japanese Red to see a glimpse of her mischievous nature in canon. It's not a perfect match but Izumi Konata would be somewhat of an example of her personality.
